Principle 2: Operable
Use descriptive titles for pages and sections
Web pages and documents should have titles that describe their function or purpose. This is helpful for all users, but is especially helpful for blind users, as the title is typically announced by screen readers as soon as a new page is loaded in the web browser or a new document is loaded in the reading application.
Best practice
Adding titles in your HTML
In HTML, the title is contained within the <title> element. This should not be confused with the main heading of the web page, which should be tagged as <h1>. The main heading is visible within the body of the web page, and the title is not. However, the title is used for other important purposes. For example:
A good title communicates the topic or purpose of the current page. When the page is part of a related collection of web pages (e.g., a departmental website) the page title should be combined with the site title. For example, the title of the current page includes both the topic of the current page and the name of the website.
